2013-09-17Remove trailing whitespace from the license headers.Ralph Giles
2013-05-20Convert quotes in license headers to ASCII.Timothy B. Terriberry
Since the last patch originally had them mangled (presumably by mailer, http server, or something else), let's just get rid of them.
2012-09-12silk: move down- and upsamplers constants to the header file.Diego Elio Pettenò
These are only being used outside if the translation unit and only in a few codepaths; by making them static in the header, the compiler can optimize them quickly. This avoids GOT-based access to the external symbol on Unix, and can allow for constant propagation to optimize the code. Signed-off-by: Diego Elio Pettenò <flameeyes@flameeyes.eu>

2011-12-13SILK fixes following last codec WG meetingKoen Vos
decoder: - fixed incorrect scaling of filter states for the smallest quantization step sizes - NLSF2A now limits the prediction gain of LPC filters encoder: - increased damping of LTP coefficients in LTP analysis - increased white noise fraction in noise shaping LPC analysis - introduced maximum total prediction gain. Used by Burg's method to exit early if prediction gain is exceeded. This improves packet loss robustness and numerical robustness in Burg's method - Prefiltered signal is now in int32 Q10 domain, from int16 Q0 - Increased max number of iterations in CBR gain control loop from 5 to 6 - Removed useless code from LTP scaling control - Optimization: smarter LPC loop unrolling - Switched default win32 compile mode to be floating-point resampler: - made resampler have constant delay of 0.75 ms; removed delay compensation from silk code. - removed obsolete table entries (~850 Bytes) - increased downsampling filter order from 16 to 18/24/36 (depending on frequency ratio) - reoptimized filter coefficients
2011-12-02Rename '_FOO' to avoid potentional collisions with reserved identifiers.Ralph Giles
C reserves identifiers of the from _[A-Z]+ and we have a number of those in the code. This patch renames the various function arguments, MACROS and preprocessor symbols to avoid the reserved form. It also removes the CHANNELS() macro altogether. This was a minor optimization for TI DSP to force a mono-only build, as were the associated local 'const' versions. Since stereo support is manditory, it wasn't worth keeping. Thanks to John Ridges for raising the issue, and Jean-Marc Valin and Greg Maxwell for reviewing the changes.

2011-03-08Support for glitchles mode switchingJean-Marc Valin
Uses a 5ms redundant CELT frame embedded into the SILK or hybrid packet to handle the switching. It's still possible to use the PLC-based method when no redundant packet is included.
